WEFTREPLENISHIN-G LIQ-0M AND MAGAZINE THEREFOR.

To all whom 'it may concern Be it known that I, WILLIAM L. 1 3A-RRELL," a citizen ofthe United States, residing at Lawrence, in the county yof Essex and State of Massachusetts, have invented new and useful Improvements in Weft-Replenishing Looms and Magazines Therefor, of which the following isa specification.

In my copending application, Serial No.A

5,221, tiled January 30, 1915i, I have shown and described a loom in'which two shuttles are interchanged whenever new iillino is. required, one of the shuttles being held in i reserve away from the shuttle box while the other shuttle is operated. I have Valso shown shuttle-loading mechanism, a magazine for weft carriers, and a chute arranged to conduct the weft carriers from the magazine into register with `the sliuttle-loading mechanisin. In that case the travel of theweft carriers from the magazine to the shuttleloadiiig mechanism is due solely to grayity.

The object of my present invention is to providea loom of the character stated with a detachable and portable magazine and with transferring means arranged to trans-` fer the weft carriers positively from the magazine into register with the shuttle-loading mechanism. Since the transferring means acts positively to carry the weft carriers, the latter are not dependent upon the force of gravity for their transfer, and the possibility of failure of operation due to sticking or disarrangement of the weft carriers is minimized ifnot wholly obviated.

Of the accompanying drawings, which illustrate one form in which the present. invention maybe embodied:

Figure 1 represents an elevation of the change end of a loom embodying some of the characteristic features of the so-called Stafford loom, such loom in the present iiistance being provided with a magazine for weft carriers and with my improved mechanism for transferring the weft carriers from the magazine into register with the-shuttleloading mechanism.

Fig. 2 represents a top plan View, partly broken out and shortened, of thel transferring means mentioned in connection with Fig. 1.

Fig 3 represents a vertical section through the structure intersected by line 3*?) of' Fig. 2. See also line 3 3 of Fig. 12.

See line 11-11 of Fig. 9. f 'Fig 12 represents an elevation, partly in section and partly broken out and shortened, of the transferring mechanism, the direction of view being indicated by line 12-12 of Fi 2.

The same refeience characters indicate the same parts wherever they occur.

Although the loom per se does not constitute the essence of the present invention, I have included enough of a loom in Fig. l to show the relation of the magazine and transferring mechanism, but it will not be necessary to describe the loom nor the mechanism by which the shuttles are interchanged, because the latter ,elements are substantially as shown and described in the said copending application, Serial No. 5,221. It will be sutlicient for present purposes to state that the reserve shuttle indicated at is in position to be charged by the shuttle-loading mechanism hereinafter described, and that the shuttle indicated at is in operative position in the shuttle box of the lay b.V The reserve shuttle rests upon a fixed support a loaded shuttle thereon, and

' view of a weft-end carrier. Each weft car I rod or vstud about which it may turn. An

arm 21 carried by the hub 18 is pivotally connected by a stud 22 with the forward end of the bar 23. T-he rear end ofthis bar is movable up and down to and from register with a striker 24 carried by the lay. As shown by Fig. `1 the bar 23 is in its lowest position, vthis being its normal position, and it is raised only when the shuttle-changing mechanism is brought into action. Although Fig. 1 includes mechanism arranged to move the bar 23 into register with the striker 24, it will not.be necessary to describe such mechanism excepting to state that during the shuttle-changing operation'the rear end of the bar 23 is moved into register with the striker 24 and that upon the rst beating-up motion of the lay following a change of shuttles the striker engages thebar 23 and moves the latter toward the front of the loom, also that upon the first backward movement of the lay the bar 23 drops from register with the striker and remains in the position shown by Figsl until the next operation of the shuttle-changing mechanism. The forward motion of the bar 23 causes the loader 17 to descend and force the bobbin' indicated at a, into the reserve shuttle It may be sta-ted.v that the bobbins and shuttles are substantially like those used in the Northrop loom' hereinbefore mentionedL The usual three wire rings .oirthe base end of the bobbin areshQ/wn in Figs. 7 and 11, but the bobbinsare represented conventionally in this respect in the other gures, for the sake of simplicity.

The bobbins are carried successively into'I register with the shuttle-loading mechanism by transferring mechanism which includes a rotary carrier 25 and an endless link belt carrier or conveyer. The carrier 25 is in most respects the same as the well-known rotary magazine of the Northrop loom, but

in this case it does not have any spring clamps for holding the bobbins. As shown by Figs. 2, 10 and 1.1, the rotary carrier coniprises two coperative disks 26, 27 ,-disk 26 being provided with sockets 26 adapted to receive the large ends a of the bobbins, and

disk 27 being provided Awith sockets 27 arranged to receive the bobbins as shown by Figs. l() and 11. The disks 26 and 27 are, to all intents and purposes, a unit, and are 4provided with hub portions 28 and 29 which are affixed to each other. This carrier is mounted upon a stationary rod or axle 30. i

Disk 26 is provided with ratchet teeth 31 by which it is rotated step by step to move the bobbins successively 'into register with the loader 17. For this purpose the loader is provided with a paWl 32 arranged to impart rotary movement to the carrier as the loader rises after forcing a full bobbin into the shuttle',` all according to the well--known operation of the loading mechanism of the Northrop loom.

The bobbins are retained in the sockets 26', 27 by a fixed curved plate 33 until they reach a position in register with the loader. In this position they are supported by a pair-of spring-pressed latches 34 (Figs. 6, 10 and 11). These latches are pivotally mounted upon a rod 35 and their free ends are normally raised by helical torsion springs 36. A These latches are so disposed as to be displaced by the bobbin at a as the said bobbin is being forced downwardly toward the shuttle w, and as soon as the bobbin has passed the free end of the latches the latter are4 returned to their normal position by the springs, where they are adapted to support the next bobbin. The plate 33 is omitted from Fig. 11 to expose other elements to view.

Each bobbin, upon being. placed in the magazine, is provided with a weft-end carrior of the form shown by Figs. 4 and 5.l This carrier consists of a single piece o of.

vfastened to the member 0 by placing it in the kerf c3, winding it one or more times around the body of the member c, and tying the end or laying it again in the kerf 03. The weftend carrier remains on the bobbin until the latter reaches the position indicated at a in Figs. 1 and 6, but before the bobbin is de' pressed by the loader 17 the weft-end carrier'V is detached from it automatically by mechanism hereinafter described..

The -conveyer comprises a pair of endless series of links 37 and 38 pivotally connected with each other by pivot rods 39. Each pivot rod extends through two contiguous links 37 and through two contiguous .links 38, and the ends of the rods project laterally beyond the conveyer and are provided with anti-friction rolls 40. These rolls travel in grooves 41, 41 formed in fixed supports 42 and 43, and roll on the bottoms of the grooves. The conveyer is driven by sprocket wheels 4a. 44 and passes over idle sprocket wheels 45, 45. These 50 with the centers of the sockets of the conanti-friction. rolls sprocket wheels are formed with notches 46 (Fig. 6) andare arranged to receive the 40 in said notches. Sprocket wheels 44 are aixed upon a shaft 47. This shaft is provided with la spur -gear 48 which is driven by a spur gear 49 carried by the rotary disk 26. *The conveyer thus receives its motion from'the rotary carrier, the spring 19 (Fig. 7 being the prime mover.

Each link 37 is formed with a socketfO, and each link 38 isformed with a socket 51. Each weft-carrier is carried by a link 1 dicated as a yWhole at 52 in Figs. 1, 3 and 12.` This magazine is arranged to rest upon the 37 and a link 38,-the socket 50 being adapted to receive the large end a. of the bobbin andl the socket 5l being adapted to receive the weft-end carrier o, as shown by Figs. 2 and 3. The spacing of the sockets `of the conveyer is equal to the spacing of the sockets 26, 27 of the rotary'carrier, and the sockets of the one register successivel' with the sockets of the other to transfer t e bobbins from the conveyerto the rotar carrier. (See Figs. 6 and 9).- As the li is of the conveyer pass around the sprocket wheels 44 they are tipped so as to discharge the .bobbins by gravity into the sockets ofthe rotary carrier, and the bobbins are retained in the latter sockets .by the curved plate 33 hereinbeforc mentioned.

The magazine for the weft carriers is insupports 42 and 43,- but is` detachable from said supports so that it may be taken away from the loom for recharging. The body of the magazine is a substantially rectangu-v lar box, and its lower edges are adapted to Venter rabbeted portions 53,l 53 of the said supports to be registered relatively to the conveyer. The magazine is divided by partitions 54 into a series'of compartments,.and the weft carriers are placed one upon another in stacks in the several compartments. When the magazine is in the desired position upon the supports 42 and 43'the several stacks of. weft carriers register respectively withthe sockets lof the conveyer. In

, other words, the centers-of the weft carriers in the magazine are in vertical alinement' veyer. Consequently when the weft carriers are discharged'from the magazine they drap' mea-ns hereinafter described, whereby those"4 of the, rear compartment are discharged virst, then those in the second compartment from the rear, and so on until those in the front compartment are discharged. The several stacks of weft carriers are initially supported by stops 55. Each stop includes a bobbin-engaging portion and a rockshaft 56. (See Figs. 3 and `12). .The end portions of ther rocksha'ft. extend through the side walls of the magazine, and one end of each rockshaft is provided With an arm 57.

'side of the magazine. Each detent has a' finger 60 arranged to be engaged and actuated by a tripping memberl. There is one such tripping member for each detent. The several tripping members areNarranged-upon but not aiixed to a rockshaft 62, said rockshaft being capable of turning under certain conditions, hereinafter explained, without moving any or all of the tripping members. Thev rockshaft is provided with a series of collars 63. These collars are pinned or otherwise afixed to the rockshaft so that they all turn in unison with the rockshaft. v

Helical torsion springs 64 are-arranged toI transmlt motion from thecollars 63 to the tripplng members 61, but lif the tripping in due course, when the rockshaft turns, such turning will result merely in deflection of the springs. i

Amembers are restrained, as will be explained The lowest weft carrier shown inFig. 3 `l is resting upon the endless conveyer, its ends being in the sockets 50, 51 provided for that purpose. A spring plunger 65 is arranged to slide in a suitable bearing formed in the support 42, and its outer end is arranged to be engaged by member 61. This plunger is normally pressedtoward the tripping member 61 by a helical compression spring 66. The inner or left-hand end of plunger 65 is-arranged to abut against the weft carrier resting on the conveyer, and so` long as there is a weft carrier in position to be engaged by the plunger thelatter will prevent the tripping device 61 Jfrom retracting the detent58 from the arm 57 There is one stop 55 for each stack of weft carriers, one detent 5 8 for each stop, one tripping member 61 foreach detent excepting that for the rear; stack, and

one restraining 'member 65 for each trippin member. The detent 58 for the rear stac tripped manually when the magazine has been placed in position upon the supports 42, 43, and the other detents are thereafter trippedautomatically as `w1ll be explained.

As shown by Fig. 1 all the weft carriers have been discharged from the rear compartment of the magazine,4 and thel weft carriers -in all the other compartments are supported by their respective stops 55. So long as there is a weft carrier on the conveyer in vertical register W1th the second the tripping of weft carriers is intended to be l compartment from the rear, the stop 55 in the second compartment will remain locked member 6l retracts the detent 58 by which shuttles is necessary.

the weft carriers in the second compartment are released. As the conveyer moves forwardstep by step, the weft carriers drop step by step and find their way successively into the sockets in the conveyer. The rockshaft 62 is operated once for each operation of the shuttle-loading mechanism, but the tripping members 6,1 are released one at a time only when their respective locking plungers 65 are left free by the weft carriers on the conveyer. The several stacks of weft carriers are thus released one after another in regular order, and the releasing operatlon 1n each case cannot occur until the last weft carrier of the preceding series has been carried beyond vertical register with the stack next in order for release.

The mechanism for operating the' rockshaft 62 is shown by Figs. 1, 2 and 12. An v.

operating arm 67 is aflixedtoy the rockshaft and is pivotally connected witlnthe upper end of a connecting rod 68, said upperend being bent, as shown by Fig. 1, to a'ord such connection. The lower end of the con# necting rod is pivotally connected to a lever 69. The fulcrum member of this lever is indicated at 70. A cam 71 carried by a shaft 72 coacts with a roll 73 mounted on the lever. used fiar the additional purpose of lifting the movable shuttle-box front 74 to release the shuttle when theV shuttle-changing mechanism is brought into action. The member 74 is carried by a pair of arms such as that indicated at 75. affixed to a rockshaft 76. An arm 77 aiixed to the rockshaft is pivotally connected to the upper end of a rod 78. `The lower end f ofth'is rod is pivotally connected to the forward end of the lever 69. A helical tension spring 79 is connected to one of the 'arms 75 and normally keeps the roll 73 in contact with cam 71. Shaft 72 is commonly known as the change shaft in looms oftheI type shown, and operates lonly when a change of When a shuttlechanging. mechanism is brought into operation the change shaft describes one revolution and is then automatically stopped, and it is at such times that the'connectingrod 68 is moved to turn rockshaft 62 to release a stack of weft carriers in the magazine, provided such release is in order.

In the present instance lever 69 'is' These arms arev The description up to this pointy is complete as to the magazine, the discharge of weft carriers `from the magazine to the conveyer, the transfer of weft carriers from the 80A (Fignl) which interchanges' the shutf- .tles. This carrier is substantially the same as that shown in the aforesaid copending application, but a brief description of it will be necessary forzpresent purposes. This carrier` includes an oscillatory arm 81 mounted upon a fulcrum/stud 82. A roll 83 carried by the 'arm coacts with a cam 84 on the change shaft 72. A helical tension spring 85 is connected to the arm and exerts its tension to move the carrier toward the Flay in accordance with the contour of cam 84. The return motion of the carrier is effected positively by the cam. As shown by Fig.' 1 the carrier is in itsextreme forward positiomto which it moves after depositing a spentr shuttle on the suppbrt 15. The extra forward travel of the carrier after depositing a spent shuttle is utilized to set the detaching mechanism in positionto get hold of a weft-end holder. For this purpose the carrier is provided with a member 86`whichv rides oyer and depresses a roll 87. This roll is mounted upon an arm 88, and thesaid arm is affixed to a rockshaft 89.l A bevel gear 90 aixed to shaft 89` coacts with a bevel gear 91 fastened to shaft 92. ferring to Figs. 2, 9 .and 10, -a'n arm 93 `is affixed to the upper end of shaft 92 and has pin-andslot connection with an arm 94. In the present instance the pin' is carried by arm 93 and is indicated at 95, andthe slot is formed\in arm 94 and is indicated at 96. The fulcrum member of farm 94 is indicated at 97. The Ifree endof arm 94 extends loosely through an opening formed lin a slide 98. This slide is arranged to move back and forth on a rod 99. .Any suitable provision'maybe made for preventing the slide from turning about the axis of rod 99,

,and for this purpose the rod is preferably made square in cross section, as shown best by Figs. 8 and 9.7 Theslide is provided with occupies the position shown by Figs. 2 and l0. Upon operation of the ShuttTe-changing mechanism the shuttle carrier moves tothe rear, thus releasing the roll 87 `A hellcal torsion spring 89 (Fig. 10) 1s thus pervmitted to turn rockshaft 89 to impart stripping motion to the stripper1 as indicated by arrows on slide 98 in Figs. 2 and 10. The detachable member c of the weft carrier which is then in register withthe shuttleloading mechanism is thus stripped from the smaller end of the bobbin, and drops into a trough 101. The travel of the slide 98 is suiicient to carry the member c beyond the outer end of the trough, and the member c is consequently discharged from the trough and may drop into a suitable receptacle (not shown).

Inasmuch as the weft end is fastened to the weft-end carrier when the latter is discharged, a few convolutions of the weft are unwound from the bobbin and are drawn through a slot 102v formed in the bottom of the trough 101. The outer end of the shuttle support 15 is ing wall 15 whereby the spent shuttle is registered relatively to the loading mechanism. This wall 15. is provided with a sloti 103 the upper end of. Which registers with the aforesaid slot in the trough 101.

Figs. Swand 9). The stretch b of weft running from the bobbin to the weft-end carrier 1s thus drawn into the slot 102 and heldl therein-by the discharged weft-end carrier. The weft-end carrier draws the weft end to the lower end of the slot 103, and the weft end is thus caused to bear upon the shuttle as shown by solid line in Fig. 13. When the loaded shuttle is carried by carrier` from` the support 15 to the shuttle box of the lay, the stretch b of weft running from the shut-- tle to the slot 103 of the shuttle support. moves across the outer end of the shu-ttle and is drawn laterally into the throat m2 of the shuttle as indicated by dotted lines in Fig. 13.A The `shuttle is thus threaded while on its way to the shuttle box of the lay.

An arm 104 is aiixed to rockshaft 89 and is arranged to confine the shuttle in bobbinreceiving position on/the support 15. The `arm 104 drops when the shuttlecarrier 80 moves to take up the loaded shuttle, and remains below the path traversed by the shuttle during the interchanging operation until the ycarrier80, after having deposited the spent shuttle on the support 15, engages and depresses the roll 87. The stripper remains in its outer position during the interchange of shuttle but is returned to its inprovided with an upstand- (See the operation of the shuttle-chang- Upon the' completion of the cycle of -the shuttle-changing mechanism Nthe change shaft' stops and the weaving mechanism of the loom starts in consequence of automatic controlling means (not shown) as in the Stafford loom. It is to be noted that the bobbin at a has had its weft-end holder a removed, and that the stripper 1001 has been returned to its initial position. Consequently upon the first beating-up stroke of the lay the bobbin at a is ready to be driven into the spent'shuttle, andupon the -next step of the rotary carrier 25 the stripper 100 is in position to register with the nextfbobbin whichreplaces that at a. The pin 109 of the bar 23 is'disengaged from the latch 108 by the forward movement of the bar, and the latter drops during the rst traverse of the lay to the rear.
